Extended Travel Ball Bearing Drawer Slides

HA3504 60kg double stacked drawer slides

This is a slide built for drawers that need to reach further than they normally would. Its core idea is simple: when a drawer has to extend beyond the slide's own length, the double-layer ball bearing structure takes over the load, bringing items at the very back into plain view and easy reach. With a 60kg load capacity, it suits tool cabinets and medical equipment where stable support matters. The non detachable design means the rails stay on track after installation, without unexpected separation during movement.

It doesn't chase extra features. It focuses on one thing: making sure tools, instruments, or materials stored deep inside a cabinet can be fully presented when they are needed

Non Detachable Structure Offers a stable and reliable connection.

Extended Travel Pulls the drawer farther out for easier access.

The ball bearing action can create a quiet environment at work.

Nylon buffer can reduce the direct contact between the outer and the inner channel.

1. Is HA3504 faster for emergency medical drawers?

The main advantage of the over-travel design is not the opening speed, but how quickly the contents can be accessed. When the drawer is fully extended, the items are easier to see and reach, reducing the time spent searching during urgent situations.

2. Is HA3504 resistant to impact?

The non-detachable structure can provide some additional stability because there are fewer connection points between the slide sections, reducing the risk of accidental separation or misalignment during impact. However, repeated impacts can still transfer loads to the balls and tracks and cause wear. For carts used on uneven floors, reducing the travel speed or adding suitable cushioning measures is recommended.

3. Is 1.5 mm steel too thin for a 60 kg slide?

A 1.5 mm steel thickness is within the typical range for 60 kg-class industrial slides, offering a practical balance between structural strength and overall weight. With the double-stacked ball-bearing structure, the load is distributed across multiple contact points, so the thickness of a single steel section does not determine the overall load capacity on its own.
